ABSTRACT:
A vented battery cap is provided which is adapted to engage at least one of a plurality of fill holes in an automotive storage battery or similar lead acid battery and which has pressure release means for venting the combustible gases produced within that storage battery under conditions such as overcharge conditions into the atmosphere, said pressure release means comprising a plurality of extremely narrow slits having widths in the order of 0.003 to 0.005 of an inch. The remainder of the battery cap is tightly sealed to prevent any extraneous leaks of battery gases received from the automotive battery from leaking into the atmosphere. The slits are so constructed to facilitate the safe expulsion of any volume of gas normally produced by an automotive storage battery, while virtually eliminating the likelihood that ignition of gases within the atmosphere will result in explosive consequences either within the battery cap or within the battery itself.
